The balls rotate with high energy inside a drum and then fall on the solid with gravity force and crush the solid into nano crystallites. CONCLUSION The significant advantage of this method is that it can be readily implemented commercially. Ball milling can be used to make carbon nanotubes and boron nitride nanotubes.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

The major use of the conventional ball milling is to fracture the particles and to reduce the size, which is different from the newly established high energy ball milling (HEBM) method. In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy is much higher than the conventional ball milling

High-energy ball milling is a convenient way to produce nanosized powders. It is the most common method reported in the literature for the synthesis of intermetallic nanoparticles. Before a mechanical milling is started, powder (s) is loaded together with several heavy balls (steel or tungsten carbide) in a container.

Licari et al. used different mechanical deconstruction methods (tumbler ball mill, vibratory ball mill, centrifugal mill, and jet mill) for pretreatment of sugar cane bagasse. The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield.

In this method, inert, nontoxic milling media such as resin, glass, or stabilized zirconium oxide is added to the raw material and carrier liquid for milling. The mill’s action — for example, the motion of a grinding bowl in a high-speed planetary ball mill — generates high-energy shear forces to fracture already small particles into nanoparticles as they circulate with the grinding media.
